圪塔河中桥是榆次龙白—祁县城赵高速公路在榆次北田镇巩村东约500 m处跨越圪塔河而设。此桥采用3~20 m装配式预应力砼连续箱梁,桥梁中心桩号为K24+748,右前夹角为90°,全桥1连;下部结构采用柱式台、柱式墩,基础采用钻孔灌注桩基础。设计桩长按小桩号到大桩号顺序为:43～47～50～43 m,其直径Φ1 500 mm,为摩擦端承桩,桩基施工完毕后,对其24根桩进行了“声波透射法”无破损检测,桩的完整率达到100%。
Qiongtai River Bridge is Yuci Longbai - Qixian City Zhao Expressway in Yuci Beita Zhen Gongcun East about 500 m across the Qiongtai River and set up. The bridge uses 3 ~ 20 m prefabricated prestressed concrete continuous box girder, the bridge center stake for the K24 +748, the right front angle of 90 °, the whole bridge 1; the lower column structure using column, column pier, the basic use of Bored pile foundation. The length of the design pile from the small pile to the large pile is in the order of 43 ~ 47 ~ 50 ~ 43 m and its diameter is Φ1 500 mm, which is the friction bearing pile. After the construction of the pile foundation is finished, Acoustic transmission method "no damage detection, pile integrity rate of 100%.
